Juliana is in a fix these days. One fine morning when she was doing her work on her laptop, her little brother came up and asked the password of her smartphone so that he can play his gaming stuff. Juliana was busy at that time and wanted to concentrate more on her work so she just uttered the password. Later she realized that now her password is open and hence along with many things her WhatsApp chat is also not secure. Even if Juliana changes her password which locks her mobile, there is no guarantee that she will not repeat her mistake. Juliana can only wish about a separate locking system for WhatsApp.
